lost a partition

We had a situation today that a co-worker trashed one of the drives that contained data. We have it set up with a program disk called it a name and them we have dataA and data B
One of those drives got mixed up on the desk top with a group of images that had been opened on the desktop. The trash was emptied and then it was noticed we were missing data A.

Can this information be recovered? It is an issue of to many icons on the desktop and then dragging and deletion. Does anyone have suggestions or ideas to revtrive the files?

About the only way to recover this is to have ProSoft Engineering's Data Rescue as a bootable disc and stop using the computer instantly you notice the data missing.

Once you are sure you have emptied the trash, the data residing on that disk is not yet deleted. It is however open to rewrite over. So if it is not an the active drive, such as the drive the operating system is on, you will have a chance to recover the data if you don't access the other drive (assuming there is more than one disk drive.)

Load the Data Rescue CD and let it boot your MAC back up and start the recovery process. You also need a place for DR to put the found files.
